    Does anyone know if there is a setup that uses a power steering pump to also operate power brakes?

  4. My 1983 GMC (Diesel) Suburban had a power brake booster that used the steering pump. The older diesels do not produce enough manifold vacuum (it's an efficiency thing...) for a standard power brake booster.

    My '05 GMC 4500 has a combo power brake/power steering unit. Heavier, (1 ton and up) Ford trucks use a similar set up.

    GM trucks and some G vans. as an alternative you can also buy vacuum pumps
     
  8. Early diesel Cadillac Eldorado used Hydorboost. Thats the system that I have on my 32 Chevy....Works great with a hot cam that produces low vacuum and easily adapted for under floor mounting. You car read more here.

    My 85 Pontiac full size wagon was that way. I think the 90 Olds was also.

    My 99 Cobra has it and have seen it advertised in after market systems.
     
  13. Lots of big BMWs have used hydraboost since the late 80s
